| Abstract: | The solid samples of analgini were analyzed noninvasively by means of conventional and first derivative near-infrared diffuse reflectance spectra. The quantitative prediction abilities of partial least squares methods in both cases were compared. The influence of the calibration samples and wavelengths on the Capacity of PLS are discussed. The relative standard errors of prediction for the calibration samples and prediction samples with conventional spectra are 0.9891% and 1. 463 0%,while those with derivative spectra are 0. 110 2% and 1. 042 9%, respectively. |
